Target cost version 0 is active but not showing target cost for some plants

Summary:

When I analyze actual costs on production order using CO03, while the target costs are visible for production orders for some of the plants, it is not visible for any of the production orders for other plants.

Since target cost version is activated at the controlling area level using OKV6, what else needs to be done to get it working for those other plants?
